Reducing Your Exposure to PFAS

Reducing Your Exposure to PFAS

Nearly everyone in the United States has been exposed to PFAS and likely have PFAS in their blood, especially perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), according to the Agency for Toxic Substances and Disease Registry (ATSDR). PFAS chemicals have been used in industry and consumer products worldwide since the 1950s. These forever chemicals are prevalent in non-stick cookware, water-repellent clothing, stain resistant fabrics and carpets, some cosmetics, some firefighting foams, and products that resist grease, water, and oil.
